AI-suggested

A patch is available and should be applied to affected Linux kernel versions. The fix is included in kernel versions 5.4.0-1147.157~18.04.1 and later as listed. Users should update their systems to these fixed versions or later to remediate the vulnerability. After updating, a system reboot is required to apply the kernel changes. No additional mitigations are indicated by the vendor advisory.

Description

CVE-2024-58093 is a high-severity vulnerability in the Linux kernel's PCI/ASPM subsystem involving improper handling of link state during the removal of upstream functions on PCIe switches. The flaw could cause use-after-free conditions leading to general protection faults (GPFs), especially during device hot-unplug events. The issue arises from incorrect timing of freeing ASPM parent link state when removing functions on a PCI bus. This has been fixed by adjusting the free operation to occur exactly when function 0 is removed, preventing premature or delayed freeing of link state.
